I don't think that you can devise a locking scheme that would be foolproof and allowed callers to poke into fields of a submitted URB (such as ->status). But go on, surprise me. That many drivers are broken is not as bad as it sounds. Most of them do have callbacks already and do sleep, therefore they already have some data structures which can accomodate a "done" flag (same that contain waitqueue). It's not like we would need to do a major surgery. -- Pete _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
